Visions in Psychotherapy Research and Practice [PDF ebook] 
Reflections from Presidents of the Society for Psychotherapy Research

The Society for Psychotherapy Research (SPR) is devoted to the development and dissemination of research, as well as the integration of empirical, theoretical, and clinical knowledge in psychotherapy. A highlight of the SPR annual meeting is the presidential address, wherein the president delivers what many view as the most important presentation of their career. In Visions of Psychotherapy, Bernhard Strauss, Jacques Barber, and Louis Castonguay, three recent past presidents, compile the preceding 20 presidential addresses from SPR into a single volume. Then, the living presidents (19 of the 20) comment on how the visions they described in their addresses have developed over time.
